Robert Boyd, the developer behind hit indie RPGs Breath of Death VII and Cthulhu Saves the World, says he's made more revenue from the games in a week of Steam sales than in months of Xbox Live Indie Game sales.

Both titles were released last week on Steam as a bundled two-pack which briefly reached the No. 1 sales position on the digital download service, leading Boyd to call the launch a "tremendous success."

On the Zeboyd Games blog, Boyd shared the news that the titles are selling far better on Steam than they did on Xbox Live Indie Games.

"We are pleased to announce that Zeboyd Games has already made more revenue in less than a week on Steam than we have in over a year and a half on the XBox Live Indie Games service," he said.

Breath of Death VII launched on XBLIG last April, with Cthulhu Saves the World hitting the service late last December. Boyd revealed lifetime sales figures for the Xbox versions earlier this month, saying Breath of Death VII has sold 50,000 copies at $1 each, while Cthulhu Saves the World has sold between 16 and 17,000 at $3 each.

Those sales numbers would imply the $3 Steam bundle has brought in over $100,000 in the space of its first six days on sale, representing over 30,000 bundle purchases.

In a Gamasutra blog post last September, Boyd showed XBLIG sales of Breath of Death VII spiking after launch and surrounding media coverage before eventually tapering off to the neighborhood of 100 sales per day.
